Description

The Cecilware F178AL Thermopile is an electrical sensing part that is used to replace a component in gas-fired commercial equipment. It has a length of 36 inches and yields between 250 and 750 millivolts under a pilot flame. It is installed in the gas control circuit and produces the power needed to open safety valves and confirm the presence of flames. This assists in having better control of the flow of gases and closing the flow when ignition is lost. The thermopile is commonly used in professional foodservice equipment to support the safe operation, ignition and steady performance of the appliances.
